IMPROVEMENT INl FLOUR-BOLTS.

Specication forming part of Letters Patent N0. 181,095, dated August 15, 1876; application led May 31, 1876.

To all whom it may concern:

Be it known that IhWILLIAM D. MURRAY,

` of Hamilton, in the county of Caldwell and State ot' Missouri, have invented a new and useful Improvement in Flour-Bolts, ot' which the following is the specification:

This invention relates to an improvement in that class of flour-bolts' in which the bolting-cloth is attached to a reciprocating frame.

The improvements relate, first, to the man- 11er of attaching the sieve or frame of' the bolt to adjustable supports ,'seconclly, to a series of stops or rods for stirring up the our while in the bolt; and, thirdly, to an adjustable tailboard, by means ot' which the boltingoperation may be partially adjusted.

rlhe invention will be readily understood by reference to the accompanying drawings, ot' which- Figure 1 is a side elevation of the improved bolt or sieve. Fig. 2 is a plan ot' the same. Fig. 3 is a rear-end elevation ol' the sieve frame.

The bolting-chest A has four adjustable posts, B, which are attached to the said chest by means ofthe screws or bolts a., that move in slots a', so as to set the said posts in different positions, which may be either directly vertically, or inclined either forward or backward, so as to either accelerate or retard the bolting operation. To the top ends ofthese posts B are attached, by suitable pivot-joints b, the swinging rods B, by means of which the bolt or siy'e frame U is suspended, so as to receive the vibrating or reciprocating inotion from the driving-rods D, which may receive a reciprocating motion from suitable cranks or cams. Across the sieve or bolt frame O, and just above the cloth c, are placed transverse rods Cl, which are fixed to the sides ofthe said frame C. These rods act on the contents ofthe 'bolt or sieve to stir up the same, and thereby thoroughly' separate the bran from the liour. The tail-board G2 is attached to the frame G by means of' screws or bolts c1, which move in slots c2 in the said board G2, so that the said board may be adjusted and set at different heights, for the purpose of properly regulating the degree of closeness to which the tlour may be separated from the bran.

Having described my invention, 1 claimrIhe adjustable standards B, links B', pivoted thereto at their upper ends, set-screws a, and slotted supports A, substantially as and for the purpose set forth.
